Title (EN) RECOIL SPRING ASSEMBLY
(FR) ENSEMBLE DE RESSORT DE RECUL
Abstract: front page image
(EN)In the field of spring assemblies for crawler type vehicles, the servicing and/ or replacement of recoil springs in the field is of ten difficult and dangerous since the springs require large preloads and the equipment required to service the springs is not readily conveyable to the field. The object of this invention is to provide a spring which can be serviced and/or installed in vehicles in the field. The spring assembly (20) for use in a crawler type track roller frame (12) includes an elongated tubular housing (28) having opposite open ends. A stop (36) at least partially closes one of the ends with a compression coil spring (30) being received within the housing and abutting the stop. A radially inwardly directed flange (48) on the other end of the housing has an inner diameter greater than the outer diameter of the spring for insertion of the spring (30) therethrough, but smaller than the outer diameter of a split retainer (60) (62) which supports an additional stop (52) for the spring (30). The two spaced stops (36) (52) sandwich the spring (30) therebetween and are axially movable to preload the spring (30).
(FR)Dans le champ des ensembles de ressort pour des vehicules a chenilles, l"entretien et/ou le remplacement de ressorts de recul sur les lieux de travail est souvent difficile et dangereux puisque les ressorts necessitent de fortes charges prealables et l"equipement necessaire pour l"entretien des ressorts n"est pas facile a rassembler sur les lieux de travail. L"objet de l"invention est de fournir un ressort qui peut etre entretenu et/ou installe dans des vehicules sur les lieux de travail. L"assemblage de ressort (20) pour l"emploi dans un bati de rouleaux de chenilles (12) comprend un bati allonge tubulaire (28) ayant des extremites opposees ouvertes, Un arret (36) ferme au moins partiellement une des extremites avec un ressort de compression en spirale (30) lequel est recu dans le bati et s"appuie contre l"arret. Une flasque (48) dirigee radialement vers l"exterieur sur l"autre extremite du bati possede un diametre interne plus grand que le diametre externe du ressort pour l"insertion du ressort (30) mais plus petit que le diametre externe d"un dispositif de retenue fendu (60) (62) qui supporte un arret additionnel (52) pour le ressort (30). Les deux arrets espaces (36) (52) prennent le ressort en sandwich et sont amovibles axialement pour la charge prealable du ressort (30).
